Too many athletes dwell on mistakes immediately after they make them. In competition, your job is to refocus your concentration on the task at hand and to leave your mistakes and errors behind you. Focusing on mistakes and giving yourself a hard time for them will only cause you to mess up even more. Think about and work on your mistakes after the competition, in practice, not during the game. "Make" a mental mistake folder where you can put all your mess-ups during the game and reassure yourself that you will take the "mistake folder" out and work on those errors later, when it's the right time. Quickly letting go of mistakes and refocusing are the two mental toughness skills that champions do best.
